For easy interchangeability, the mounting footprint of these cylinders meets NFPA and JIC (Joint Industrial Congress) industry standards. All have two hydraulic ports: one to extend the piston rod and another to retract it.

Adjustable Cushion—Those with an adjustable cushion reduce shock to internal components and lessen machine noise.

No Cushion—Cylinders with no cushion have a compact size.

Compact Hydraulic Cylinders

With a small body size, these cylinders fit into tight spaces but offer similar push forces to standard hydraulic cylinders. They’re double-acting cylinders, so they have two hydraulic ports—one to extend the piston rod and another to retract it. No matter the direction they’re moving, they can operate at nearly full force. This allows them to both push and pull multi-ton loads. All have a magnetic piston and can be used with sensors (sold separately) that electronically indicate piston position. Mount sensors to the cylinder with mounting brackets (sold separately).

Tie Rod-Mount Proximity Switches

Image of Product. Front orientation. Proximity Sensors. Sensor-Ready Hydraulic Cylinders.

Send an electronic signal to your system when the piston reaches a certain location. Mount one or two of these sensors on a cylinder tie rod; they must be flush against the cylinder tube. An LED indicator shows the piston location. These switches are PNP (also called "sourcing") output, so they send energy onwards. PNP output is most common in solid-state relays and PLCs used in the United States and Europe.

Rated for pressure up to 10,000 psi, these seals withstand the highest pressure of our piston seals. They have two high-strength backup rings that protect against extrusion.

Note: Maximum performance values cannot be achieved simultaneously; for example, speed is affected by pressure, temperature, and other operating conditions.
